Consider a campaign that utilizes the entire map but moves from battle to battle on that map. The battle for Hue ( as you know ) lasted over a month. You could use the entire map for some or snip it into smaller map sections for a specific engagements using the cut and paste feature of the extended map editor

This was one of my reference maps. I found three good ones, used the map utility for the contouring and then compared and contrasted the old maps with the new ones to see what was/wasn't there in 68. I also used Google Earth to check out vegetation, which I again compared and contrasted to the military maps.

I've visited the city, and especially around the Citadel, it would be a helluva place to have to assault.
Checked in here (after several years) to see if I could try my hand at fighting the battle.
It would certainly be a very different sort of Vietnam scenario (more like Stalingrad) and is arguably the major battle of Vietnam (American) war.
